if you're loading this from resources, I think it's better off to be a local
variable instead of a constant (mPlaceholderAnimationDistanceDp)

Done.

[Ted C, 2013/03/07 18:28:09]

now that these aren't statics, you probably don't need these isEmpty() checks as
they'll always be empty at construction time.

Done.
